Datastar Noob Question

How can I get a ChatGPT like UI using datastar without sending the entire page in each fragment?

Setup

Install FastAPI via pip:

pip install -r requirements.txt

Start fastapi server:

fastapi dev app.py --port 8000

Then navigate to localhost:8000

You should see this:

Where lorem ipsum is generated using server sent events powered by datastar on the frontend. The issue I have is that I could not get this to work by only sending individual words via data: merge append_element

So then on the append branch (git checkout append) I try to avoid this by using the data: merge append_element. Which sort of works in that my data being sent is much lower, however, it ends up almost crashing my browser and being very choppy.
